Benefits of technology

[0012]In view of the foregoing, it would be desirable to minimize a potential risk that may originate from the charging columns on account of damage, even

Problems solved by technology

However, such an AC charging mode is extremely restricted in terms of charging speed on account of the connection power available, generally not more than 16 A or 32 A, and on account of an installation of the charging device with sufficient power.
In modern electric vehicles, this results in charging times of several hours to be able to travel 100 km.
In the event that charging columns use the mentioned high voltages of up to 1000 V and at the same time the corresponding charging columns are generally available in locations directly accessible for vehicles, there is the risk that the charging columns are damaged by v

Embodiment Construction

[0037]FIG. 1 shows an electric vehicle 100, which is connected to a charging column 10 by a charging cable 110. In the case of an extensive installation of charging columns 10, it should be assumed that, on the one hand, the charging columns will no longer have in each case a canopy, like in conventional filling stations and, further, a plurality of said charging columns are generally installed in charging parks, which are intended to be freely accessible for the respective vehicles to be charged. As a result, the charging columns 10, the charging cable 110 and the electric vehicle 100 are always located in the open, where they are exposed to all conceivable external influences. Since it is sought, at the same time, to enhance vehicles to enable higher charging speeds from the previous 400 V to 800 V, charging columns, in particular fast DC charging columns, which use voltages of up to 1000 V are provided. On account of the high voltage, a higher power can be transmitted at the same...

Abstract

A sensor for identifying a mechanical deformation of a housing of a charging column configured to charge an electrical energy store of an electrically driven vehicle. The sensor includes an elongated arm having a first end portion arranged in the longitudinal orientation and a second end portion opposite the first end portion in the longitudinal orientation. The arm is connected at its first end portion to a base of the charging column and runs in the longitudinal orientation approximately parallel to a part of the charging column that is sensitive to deformations of the housing, in particular to a side wall of the housing. An electrical probe element is arranged on the second end portion of the arm. An activation element is connected to the part of the charging column that is sensitive to deformations of the housing and is configured to activate the electrical probe element.

Description

CROSS-REFERENCE TO RELATED APPLICATION[0001]This application claims priority to German Patent Application No. DE 10 2017 115 507.4, filed Jul. 11, 2017, which is incorporated by reference herein in its entirety.FIELD OF THE INVENTION[0002]The present invention relates to a sensor and to a method for identifying a mechanical deformation of a housing of a charging column configured to charge an electrical energy store of an electrically driven vehicle. The present invention further relates to a corresponding method and to a charging column fitted with a sensor according to aspects of the invention.BACKGROUND OF THE INVENTION[0003]Modern electric vehicles generally allow two charging modes. A vehicle has a so-called on-board charging device for charging at a desired AC voltage or three-phase socket, said charging device controlling both the required conversion to direct current and a charging operation of a battery comprised by the vehicle. However, such an AC charging mode is extremel...
